Find the 50th term of the A.P. 5, 11, 17, 23, .......

The correct answer is Option (2) → 299

In an A.P., each term is the first term plus the common difference added once for every step after the first: \(a_n=a+(n-1)d\).

• First term \(a=5\); common difference \(d=11-5=6\)

• The 50th term is 49 steps after the first: \(a_{50}=5+49\times6=299\)
